Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle 2 tablespoons of coconut oil over the cut sides and sprinkle with salt. Place the squash cut-side down on a baking sheet and roast for about 30-40 minutes, or until tender. Once done, let it cool slightly before using a fork to scrape out the strands into a large bowl.
In a large skillet or wok, heat the remaining 2 tablespoons of coconut oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Add the red bell pepper, jalapeño, and grated carrot, cooking for an additional 3-4 minutes until the vegetables are tender.
Push the veggies to one side of the skillet and add the shrimp to the other side. Cook for 3-4 minutes until the shrimp are pink and opaque, stirring occasionally to combine with the veggies.
In a small bowl, whisk together the cashew butter, lime juice, liquid aminos, maple syrup, red chili sauce, and grated ginger. Pour this sauce over the shrimp and vegetables, stirring to coat everything evenly.
Add the roasted spaghetti squash strands to the skillet, tossing everything together to ensure the squash is well coated with the sauce. Cook for an additional 2-3 minutes until heated through.
Remove the skillet from heat, and sprinkle the chopped raw cashews on top. Serve hot, garnished with extra lime wedges if desired.
